Build Status PyPI PyPI PyPI

The Plivo Python SDK makes it simpler to integrate communications into your Python applications using the Plivo REST API. Using the SDK, you will be able to make voice calls, send SMS and generate Plivo XML to control your call flows.

Installation

Install the SDK using pip

pip install plivo

If you have the 0.11.3 version (a.k.a legacy) already installed, you will have to first uninstall it before installing the new version. pip install --upgrade plivo might not work depending on your system status.

Alternatively, you can download the source code from this repo and run

python setup.py install

We recommend that you use virtualenv to manage and segregate your Python environments, instead of using sudo with your commands and overwriting dependencies.

Getting started

Authentication

To make the API requests, you need to create a RestClient and provide it with authentication credentials (which can be found at https://manage.plivo.com/dashboard/).

We recommend that you store your credentials in the PLIVO_AUTH_ID and the PLIVO_AUTH_TOKEN environment variables, so as to avoid the possibility of accidentally committing them to source control. If you do this, you can initialise the client with no arguments and it will automatically fetch them from the environment variables:

import plivo

client = plivo.RestClient()

Alternatively, you can specifiy the authentication credentials while initializing the RestClient.

import plivo

client = plivo.RestClient(auth_id='your_auth_id', auth_token='your_auth_token')

If you expect to make a large number of API requests, re-use the same client instance, but if you expect to create a client on an on-demand basis, you can use a context manager to automatically frees all resources used by the client

import plivo

with plivo.RestClient() as client:
  pass # Do something with the client

The basics

The SDK uses consistent interfaces to create, retrieve, update, delete and list resources. The pattern followed is as follows:

client.resources.create(*args, **kwargs) # Create
client.resources.get(id=resource_identifier) # Get
client.resources.update(id=resource_identifier, *args, **kwargs) # Update
client.resources.delete(id=resource_identifier) # Delete
client.resources.list() # List all resources, max 20 at a time

You can also use the resource directly to update and delete it. For example,

resource = client.resources.get(id=resource_identifier)
resource.update(*args, **kwargs) # update the resource
resource.delete() # Delete the resource

Also, using client.resources.list() would list the first 20 resources by default (which is the first page, with limit as 20, and offset as 0). To get more, you will have to use limit and offset to get the second page of resources.

To list all resources, you can simply use the following pattern that will handle the pagination for you automatically, so you won't have to worry about passing the right limit and offset values.

for resource in client.resources:
    print(resource.id)

Examples

Send a message

import plivo

client = plivo.RestClient()
message_created = client.messages.create(
    src='the_source_number',
    dst='the_destination_number',
    text='Hello, world!'
)

Make a call

import plivo

client = plivo.RestClient()
call_made = client.calls.create(
    from_='the_from_number',
    to_='the_to_number',
    answer_url='https://answer.url'
)

Generate Plivo XML

from plivo import plivoxml

xml_response = plivoxml.ResponseElement()
xml_response.add_speak('Hello, world!') # or add(plivoxml.SpeakElement(text))

print(xml_response.to_string())

This generates the following XML:

<Response>
  <Speak>Hello, world!</Speak>
</Response>
